1.3 Description
The TI MSP430™ family of ultra-low-power microcontrollers consists of several devices featuring different
sets of peripherals targeted for various applications. The architecture, combined with five low-power
modes, is optimized to achieve extended battery life in portable measurement applications. The device
features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to
maximum code efficiency. The digitally controlled oscillator (DCO) allows the device to wake up from low-
power modes to active mode in less than 6 µs.
The MSP430FE42x series are microcontroller configurations with three independent 16-bit sigma-delta
ADCs and an embedded signal processor core used to measure and calculate single-phase energy in
both 2-wire and 3-wire configurations. Also included are a built-in 16-bit timer, 128-segment LCD drive
capability, and 14 I/O pins.
Typical applications include 2-wire and 3-wire single-phase metering including tamper-resistant meter
implementations.
